DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The invention relates to a glazing system for facades, glass enclosures, roofs and windows. The glazing system is of the type in which the glass elements consist of glass panes in several layers, so-called insulated glass, and where the elements on the outside are joined edge to edge with an intermediate joint compound but generally without any outer frame element.
STATE OF THE ART
A glazing system of this type is known from DE-A1-3439436 (Schuco). In this the elements consist of two panes of glass which are joined around a distance strip by means of a sealing compound adhering to the glass surfaces. Outside of this joint the glass panes extend outwardly a short way, whereby a track is formed between the panes all around the glass element. The panes are attached to a supporting beam framework by one of the attachment elements being inlaid into said track and pressed in towards the edge of the inner glass pane by means of a screw connection with the framework. In this way the inside of the inner pane is pressed towards support battens on the framework which are located directly opposite said distance strip.
With this construction, the edge of the inner pane will be subjected to a bending moment when the attachment element is pressed towards the edge at the same time as the glass pane, at a distance from this, is pressed towards the framework. This results in a risk of breakage of the glass pane, so that the attachment by means of the attachment element is lost. A further disadvantage is that the glass edges on the element are unprotected when this is handled separately for assembly. This results in a large risk of damage during its handling even if the panes are of toughened glass since such are particularly sensitive to being struck on the edge.
Another glazing system is known from DE-A1-3626194 (Schuco). In this the attachment of the glass elements occurs in that attachment elements have been glued to these with a joint compound. The attachment elements are, in turn, attached to the framework by means of screw connections. With such a construction, the risk arises that the glue connection between the attachment element and the glass element will loose strength, whereby it has happened that glass elements have loosened and fallen down from the facade. Moreover the attachment elements are large and bulky since they have to extend a longer distance along the glass edge in order that the glue connection will have sufficient strength.
SUMMARY OF THE INVENTION
With the system according to the invention, the attachment occurs by means of attachment elements of limited size screwed to the framework, said elements being pressed towards the glass edge of the innermost pane directly facing support surfaces arranged on the framework. In this way no bending forces occur in the edge of the glass pane. Moreover a protector against knocks at the edge of the glass during separate handling is provided, said protector constituting at the same time a lining in the attachment joint.
Additional advantages will be clear from the following description of a preferred embodiment and additional features of the invention are defined in the appended claims.
DESCRIPTION OF THE FIGURES
Two variations of a preferred embodiment of the invention will now be described with reference to the accompanying drawings in which
FIG. 1 shows a partial view of the two meeting edges close to the corners of two glass elements, which are attached to a vertical beam of a framework, whereby certain parts of the glass elements are sectioned along the line I--I in FIG. 2;
FIG. 2 shows, in horizontal section, the two meeting edges of the glass elements along line II--II in FIG. 1;
FIG. 3 shows, in horizontal section, how the elements can be arranged and attached to the framework in a corner of a building;
FIG. 4 shows a second variant in horizontal section;
FIG. 5 shows the second variant in vertical section;
FIG. 6 shows a horizontal section of the edges of two glass elements which are attached onto beams at a distance from
